Consideration and Approval of Construction Contract:   Pulliam Airport Concrete Ramp Joint Repair Project.

1. Approve the construction contract with Robert E. Porter Construction in the amount of $186,284.26 for the base bid only, with a 30 day contract time, subject to approval from ADOT Multimodal Planning Division, Aeronautics Group;
2. Approve change order authority in the amount of $18,628.43(10%) of the contract amount to cover potential costs associated with unanticipated items of work; and
3. Authorize the City Manager to execute the necessary documents.

Provide improved safety and infrastructure maintenance.

This project was originally budgeted in FY 2012 in the amount of $223,710.  Expenditures totalling $42,348 were projected to occur last year so a budget of $181,362 in account 270-3780-783 was entered for FY2013.  No expenditures have occurred to date, so while the budgeted amount in the current fiscal  year is less than the contract amount, the entire project amount and grant reimbursement are still available.  The project is funded by a grant from ADOT Multimodal Planning Division - Aeronautics Group in the amount of $222,030 (90% of the total project cost) with a City match of $24,670.

Public Safety, Livability, and Maintaining Reliable Infrastructure.

Yes.  Council accepted a grant from ADOT Aeronautics on February 21, 2012 in the amount of $201,339.00 to fund the project. Council approved the design contract for this project at the regularly scheduled meeting of April 17, 2012 In addition, the City will receive a grant amendment # 1 in the amount of $20,691 to cover additional project cost.

1) Approve the construction contract as presented.  This would allow for timely completion of the project; 2) Reject approval of the contract and direct staff to re-advertise for bid.  This would effectively delay the project until next year due to weather considerations.

City Council approved award of the design services agreement for this project on April 17, 2012.  That design work is now complete.  The project was first advertised for bid on July 18, 2012.  Bids were opened on August 2, 2012.  A total of two firms submitted bids for the project.  A tabulation of the 2 (two) bids received is attached and is summarized below:

Bidder	Base Bid	Bid Alternate	Total Amount Bid
Consultant's Estimate	$ 112,750.00	$ 109,750.00	$ 222,500.00
Robert E. Porter Construction	$ 186,284.26	$ 169,731.35	$ 356,015.61
Granite Construction	$ 192,229.00	$ 155,806.00	$ 348,035.00

 
Replacement of the concrete ramp joints is a routine maintenance function which seals the joints from water penetration and eliminates the potential for degradation of the subsurface soils and consequent damage to the concrete pavement.

The purpose of the project is to use the available grant funds in the most efficient manner to lengthen the service life of the concrete pavements and to avoid costly pavement reconstruction in the future.

The Public Participation Goals of Inform and Involve were used In public meetings where the City Airport Commission reviews the Airport Capital Improvement Plan and is updated monthly on project progress and impacts.
